SPECIFICATION forming part of Letters Patent No. 717,816, dated January 6, 1903.

Application filed April 21, 1902. Serial lilo. 103,851. (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR W. COOPER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in W'indows; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in fireproof windows, and more especially to improvements in the construction of sheet-metal window frames and sash, in means for supporting and securing the sash in the frame, and in devices for making tight or weatherproof joints between the sash and frame.

The'invention consists in the matters hereinafter described, and pointed out in the appended claims.

As shown in the accompanying drawings, Figure l is a sectional view of a windowframe with the pivoted sash therein shown in side elevation. Fig. 2 is a view of the inner face of the frame in its part adjacent to the sash-pivot. Fig. 3 is an enlarged cross-section takenthrough the frame and sash with the sash in its closed position. Fig. i is an enlarged horizontal section taken through the frame and sash on the line 4 def Fig. 1, showing the sash in its closed position. Fig. 5 is adetail section taken through the groove and packing-strip in the inner face of the frame, showing a modified construction of these parts.

As shown in said drawings, A A designate the vertical side parts or bars of the frame, A the lower cross-bar or sill of the frame, and A the upper cross-bar of the frame.

B indicates the sash, which is pivotally supported in the frame.

0 indicates one of the pivots by which the upper sash is supported in the frame, said pivots being located inside the plane of the sash. Each pivot G is attached to the sash by means of a bracket D, the pivot being connected with the frame by means of a bearingplate E, attached to the frame and provided with a bearing-aperture to receive the outer end of the pivot, which latter is made of considerable length and extends outwardly from the bracket to the bearing-plate, which is attached to the vertical side face of the frame at some distance outwardly from the sash.

7 Now referring to the features of construction illustratedin the frame, the same'is made of sheet metal and is of hollow or tubular construction. Each of the frame members consists of an inner sheet-metal part bent into channeled or trough form and having an integral flat inner wall a and side walls a, a and anexterior sheet-metal wall, which in the case of the bottom horizontal frame member is in" the drawings lettered 0L2 and in the case of the side and top members is lettered a. Said wall a of the lower horizontal frame member is fiat and projects beyond the side walls a a, which latter are provided with outwardly extending marginal flanges a which are engaged by U-shaped flanges on the margins of theouter wall a which are bent over and around the flanges a The wall a is also bent or folded near its side margins to form inwardly-extending flanges a which bear against the inner faces of the walls a. In the case of the vertical side members A and the top cross member A the inner and outer walls a d are made with flanges a and a in the same manner as before described; but the outer wall a is provided with a central outwardly extending vertical flange 6L6, formed by folding together the central portion of the metal of the outer wall, said flange being intended to enter the joints in the brickwork of the surrounding wall to hold the frame in place. The flanges a form shoulders which serve to facilitate the joining of the parts by holding the flanges a? firmly in engagement with the inwardly-bent margins of the outer fiat walls (I and a.

The inner flat wall a. of the top cross-piece A is shown as made oblique, the same being inclined downwardly and outwardly from the I inner toward the outer face of the frame, so

that it will fit the correspondingly-inclined upper margin of the sash B. This construceach of two sheet-metal membersnamely, an inner trough-shaped member 17 and an outer or marginal flat member I). The external and internal walls 6 of theinner member I) are parallel with each other and are provided at their margins with outwardly-bent flanges N. The flat outer marginal part Z) is provided withinwardly-folded parts, forming flanges 19 which are parallel with and fit closely within the external and internal walls 12 The side edges of said flat member b terminate in outwardly-extending flanges 19 which extend outwardly over the flanges b and are bent inwardly at their margins over said flanges b so as to rigidly attach or secure said outer members I) to the inner members I). The flanges b by their contact with the external andinternal walls of the member I) serve, in connection with the folded flanges b and 11 to afford strong interlocking joints between the margins of the members. In the case of the upper horizontal frame-bar of the sash, Fig. 3, the parts are constructed to form a groove to receive the upper edge of the glass, and this groove is extended upwardly through the top surface of the frame-bar to permit the insertion of the glass from the top of the sash. In other words, the upper frame-bar is provided with a longitudinal slot extending the entire length of the same, said slot dividing the frame-bar into two parallel bars or members. Each of said bars or members consists of trough -shaped inner parts b b and two flat outer members N. The troughshaped members 12 have outwardly-extending flanges b at theirouter margin, and. the flat parts 11 have their outer margins bent over the flanges 19 while said flat members are provided with inwardly-bent parts forming flanges b, which engage the inner faces of the external and internal walls of the inner members, this construction forming interlocking joints between the exterior and interior Walls of the trough-shaped members and the said flat members, like those before described in connection with the vertical sashbars. The inner parallel walls of the members b, which form the slot or opening for the glass, are extended outwardly and meet the inner margins of the flat members 13 b Joints are formed between these parts, shown in the drawings as consisting of inwardly-extending flanges Z3 formed by folding the walls 11 and theinwardly-bent marginal parts 17 of the said walls 6 the outer margins of the said inner walls of the part I) being clamped between the flanges b and the marginal parts I).

The construction in the sash bars described whereby the inner trough-shaped members are joined to the outer flat members thereof by interlocked parts,forming outwardly-extending flanges on said sash-bars, constitutes part of a device for forming tight or weatherproof joints between the sash and the surrounding parts of the window-frame. Said device embraces packing-strips K K,

located within grooves in the window-frames formed in or by means of stops L L, applied to the inside and outside of the frame above and below the sash-pivots. The stops L L are shown in the drawings as consisting of sheet-metal strips secured at their outer margins to the inner faces of the frame and extending inwardly parallel with the frame, so as to form the grooves adapted to receive the outwardly-extending flanges of the sash and into which the packing-strips K K are inserted and secured. The stop-strips L L, as herein shown, consist of U-shaped strips of metal applied along the inner flat members a of the frame and secured thereto by bolts 1, which pass through both folds of the U- shaped strips and also preferably through the packing-strips K. Said packing-strips K K are inserted within the grooves formed by the stop-strips L L in such manner as to fill the bottoms of the said grooves and to come in contact with the lateral flanges on the sash-bars when the sash is in its closed or vertical position. The upper stop-strip L and packing K extend along the top member of the frame and downwardly along the side members outside of the sash to points near the level of the pivots of the sash. Similarly the strip L and its packing K extend across the lower member of the frame inside of the sash and upwardly along the side members of the frame to points near the sash-pivots. As a result of this construction when the sash is swung into its vertical or closed position the outer flange of the upper part of the sash bears against the packing K, while the flange on the inner face of the sash bears inwardly against the packing K. In the particular construction shown the packing-strips Kand K consist of strands k of rubber, felt, or like yielding material and a strip 10 of sheet metal bent into a U form around the inner margin of said strand is, the U-shaped strips being made of proper size to fit within the spaces or grooves formed in or by the stop-strips L L. The boltsl are shown in the drawings as having heads at the outer faces of the strips, which are slotted for the application of a screw-driver, and as being adapted to engage at their ends with nuts Z, which are secured by soldering on the inner faces of the frame. The nuts being thus secured to the frame, which is perforated for the passage of the bolts, the latter may be removed and replaced at any time, the nuts being held in place to receive them and being immovable, so that the bolts may be readily inserted and removed bya screw-driver. The bolts Z are shown as passing through the packing-strips K K, so that they serve to secure said strips in place as well as to hold the stopstrips L L in place upon the frame.

At the outer margins of thelower cross-bar of the sash the same is shown as provided with an L-shaped flange 13, arranged to extend outwardly over the top face and downwardly over the outer face of the lower frame ICO IIO

member, said flange B being formed by outward extensions of the sheet metal of the inner and outer parts of the sash-bar.

In order that the stop-strips L L and the packing-strips K K may not interfere with the swinging of the sash, the same are necessarily terminated a short distance above and below the pivots of the swinging sash, and in order to provide means for affording tight or weatherproof joints between the sash' and frame at the intervals between the adjacent ends of the upper and lower packing-strips I provide a construction as follows: In the flat inner walls a of the frame is formed a slot M. The slot referred to. as clearly shown in Fig. 2, extends obliquely from a point near the upper end of the inner or lower stop-strip L to the lower end of the outer or upper stopstrip L, and in said slot is inserted a packing-strip N, which projects far enough from the face of the frame to bear against the flat side face or edge of the sash which is formed by the outer flat wall 1) thereof. As shown in Figs. 1, 2, and 4, the packing-strip N is held in place or supported on the wall a-of the frame by means of a U-shaped piece of sheet metal M, secured to the said wall at either side of said slot M, so as to form a groove to receive the packing N. Said packing-strip may be made in the same manner as the packing-strips K K, before describedthat is to say, it may consist of the strip of felt, rubber, or like material, and a U-shaped strip of metal m, folded around the inner edge of the same, as shown in Fig. 5. The employment of said metal strip m in this instance is not essential, however, as the cushioning-strip may be inserted directly in the groove formed by the U-shaped piece of metal M.

In Fig. 5 I have shown a modified construction in the means for supporting the packingstrip N in or upon the wall a of the frame,

said walla in this instance being provided with a slot or opening around which the margins of the metal are bent inwardly or offset, and the packing-strip being inserted in and supported by a U-shaped metal strip M the margins m of which are bent outwardly and are adapted to rest within the depression or recess formed by the offset edges of the opening in the said wall a.

It will be readily understood from the above that the margin of the packing-strip N which projects from the inner face of the frame into contact with the flat outer edge or face of the sash serves to form a tight or weatherproof joint between the side of the sash and the frame in its portion between the points at which the flanges on the sash bear against the upper and lower packing-strips K K. A weatherproof packing is thus provided between the sash and frame entirely around the sash, While at the same time the packingstrips N N do not interfere with the swinging of the sash in opening and closing the same by reason of the fact that the said strips bear against the flat adjacent faces of the sash-bars.

It will be manifest that the feature described embracing a sash having an outwardly-extending marginal flange and a frame having a groove adapted to receive the flange on the sash and containing a packing-strip against which the flange bears when the sash is in place in the frame may be used as well for a non-swinging or stationary sash as for,

the swinging sash illustrated, the groove, with its'inclosed or confined packing-strip, with the flange on the sash, operating equally in connection with both a swinging and fixed sash to form a tight joint between the frame .and sash.
